Notes: Still trying to take advantage of the moon's absence from the southern skies. As with most of this year's rainy season, not much rain, but lots of high clouds. This planetary in Monoceros needed more than one night (for the faint extensions), but I was only able to get in two nights (wanted three nights). I have to settle for this, as now the moon is "invading" the southern skies ...

V = 11.9;  Size 60"x50"

17.5" (2/2/02): easily picked up at 100x as a fairly small, round halo 
surrounding a bright mag 11.5 star.  Nice view at 280x and 380x.  The halo is 
irregularly round, ~50"x45" with a slightly uneven surface brightness and 
appears a bit thinner or pinched on the NW side.  Modest contrast gain with UHC 
filter at 100x-280x, although does not require a filter.

13" (1/11/86): bright mag 11.5 central star surrounded by fairly small, round 
disc.  Located between two mag 13 stars 0.8' E and 1.2' W.  View enhanced with 
Daystar 300 filter.  Central star is the variable V651 Mon (mag 11.3-13.5).
